! This tests the "virtual fix" for PR19561, where pointers to derived
|
||
|
! types were not generating correct code. This testcase is based on
|
||
|
! the original PR example. This example not only tests the
|
||
|
! original problem but throughly tests derived types in modules,
|
||
|
! module interfaces and compound derived types.
